Description

[Detailed Description of the Invention] The present invention relates to an improvement of the automatic threshing machine, so-called Vesta.

Generally, this type of self-propelled threshing machine is removably equipped with a threshing machine that has a first grain take-out section and a second grain take-out section, and the threshing machine can be used for threshing with the threshing machine mounted. The structure is such that transportation work can be performed with the threshing machine removed from the stand.

When carrying out seed paddy work, etc., it is necessary to remove residual paddy from the grain removal section of the threshing machine, but with conventional self-propelled threshing machines, it is relatively difficult to remove this residual paddy.

Therefore, the present invention provides a release plate (so-called cleaning port valve) on the lower surface of the valley gutter in the first and second grain take-out sections to open these gutter separately, and also provides a mechanism for removing the threshing machine from the machine base. By configuring the opening plate to move (open/close or slide) in conjunction with the opening plate to open the lower surfaces of the first gutter and the second gutter, the threshing machine on the machine stand can be opened after the threshing operation is completed. When removing from above, the opening plates on the bottom of the first and second gutter are moved in conjunction with this operation to open the bottom of these valley gutter and remove the residual paddy remaining in the gutter, for example by machine. The purpose of the present invention is to provide a self-propelled threshing machine that can take out residual paddy onto a stand detachably attached to the table and is particularly convenient during seed paddy work.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.
Fig. 1 is a side view of a self-propelled threshing machine according to the present invention, and Fig. 2 is a sectional view of its main parts. In the figure, 1 is a trunk frame, and 1 of this frame is a roller that runs on both left and right sides 2,2

Further, a machine base 3 is provided on the trunk frame 1, and a water-cooled four-stroke diesel engine 4 is mounted on one side of the machine base 3.

Furthermore, a U-shaped loop handle 6 is attached to the machine base 3 near the mounting area of the engine 4 via several support poles 5.
A side flanch lever 7, a threshing flanch lever 8, an accelerator lever 9, etc. are attached to the handle 6 via a bracket, a lever guide, etc.

Furthermore, a dustproof cover 10 for protecting the engine and 4 from dust is fixed to the pole 5 and the handle 6 with screws.

A lower grade axial flow type thresher 11 is removably mounted on the other side of the machine stand 3.

As is clear from FIG. 2, this threshing machine 11 has a handling chamber 14 formed above the inside of a machine casing 13 attached to a thresher base 12, and a large number of handling teeth 15... are formed in this handling chamber 14. A handling cylinder 16 having a shaft is mounted on a shaft, and a handling port 11 is provided in the axial direction of the handling cylinder 16.
At the same time, a receiving net 18 was stretched over the lower part of the handling chamber 14, and a swing sorting device 19 was provided at the lower part of the handling chamber 14, which was perpendicular to the axial direction of the handling cylinder 16. It is something.

Further, below the swing sorting device 19, there is a first grain take-out section 22 (partially made up of a gutter 20 and a first screw conveyor 21).
3 to 4) and a second grain take-out section 25 consisting of a second gutter 23 and a second screw conveyor 24. is provided with a winnowing device 27, and after the airflow from the winnowing device 2T passes through the air passage 26, it is configured to be exhausted to the outside of the machine via the dust exhaust duct 29 by the action of the suction/discharge seat device 28. This is what I did.

Reference numeral 30 denotes a second reducing device that returns the second grain from the transfer terminal end of the second grain removal section 25 into the handling chamber 14;
As shown in FIG. 3, it has a second thrower tube 31 and a second thrower blade 32, and is configured to return the second object into the handling chamber 14 by the wind generated by the thrower blade 32. This is what I did.

Reference numeral 33 denotes a "<"-shaped grain lifting cylinder whose lower end is connected to the transfer terminal end of the first grain removal section 22. At the tip of this grain lifting cylinder 33, fine grains are introduced into a paddy bag (not shown). A paddy throwing spout body 34 is connected thereto.

This paddy throwing spout body 34 is detachably supported by a gate-shaped support pipe 35 provided on the machine stand 3 via a substantially U-shaped mounting bracket 36, and the support vibe 35 has a paddy bag support. The arm 31 is integrally formed and connected.

This transfer device 38 consists of a feed chain 39 and a clamping rod 40.
and a chain cover 41.

Reference numeral 42 designates a straw removal duct for discharging waste straw cut by a straw removal device (not shown) attached to one side of the threshing machine 11 to the outside of the machine.

A residual paddy holder 43 is removably attached to the machine base 3 on which the threshing machine 11 having such a structure is mounted so as to be located at the lower part of the threshing machine base 12.

Moreover, on the bottom surface of the valley gutter 20.23, there are
As clearly shown in the figure, opening plates, so-called cleaning port valves 44, 45, are provided to open the lower surface of each of these gutters 20, 23.

Each of these open play) 44.45 is the gutter 20°230
A shaft 48. is horizontally suspended on the lower surface via brackets 46, 47.
By loosely fitting the proximal end cylinder portions 44a and 45a into the tube 49, the structure can be freely opened and closed.

The free ends of each of the opening plays) 44, 45 are bent into a curved hook shape to form hook-shaped portions 44b, 45b, and a leaf spring 50 elastically retains each of these hook-shaped portions 44b, 45b. , 51 are screwed to the lower surface of the valley gutter 20.23.

Moreover, the proximal end cylinder portion 44a of each of the above-mentioned open plays) 44, 45
, 45a extend outward through the machine casing 13, as shown in FIG. 3, and an opening/closing lever 52.
53 are integrally attached.

Furthermore, brackets 54 and 55 are attached to the machine base 3, with which these levers 52 and 53 come into contact when the threshing machine is detached.

Note that 56 in FIG. 1 is a transmission case, and 51 in FIG. 2 is a processing cylinder.

The present invention is constructed as described above, and its operation will be explained below.

When the shell culm that has been harvested using a binder or the like is transferred from the cutting stand 56 (see Fig. 1) to the shell culm nipping plate transfer device 38, the shell culm is transferred from the handling port 11 into the handling chamber 14. are inserted sequentially,
Rotate clockwise as shown in Figure 2.

The threshing process is carried out by the handling teeth 15 of the driving handling cylinder 16.

The unhandled materials such as grains that have leaked through the receiving net 18 after being threshed fall onto the swinging sorting device 19, and the swinging of the device 19 performs specific gravity sorting, and the fine grains are the most grains. The grains fall into the take-out section 22 and are sequentially thrown into a paddy bag (not shown) via the grain lifting cylinder 31.

Further, the No. 2 reduced product falls into the No. 2 grain removal section 25 via the No. 2 gutter 23 and the like.

Further, the third item is discharged from the tip of the dust exhaust duct 29 to the outside of the machine by the wind generated by the tumbler device 2T.

The second grain that has fallen into the second grain take-out section 25 is transferred to the second thrower blade 32 side of the second reduction device 30 by the second screw conveyor 24, and then moves inside the second thrower cylinder 31 by the blade 320 rotation. It is carried by airflow and sent from the upper end discharge port of the device 30 to the processing chamber, where it is subjected to reselection processing.

Further, the shredded waste straw is transferred to the straw removal cutting device by the feed chain 39, and then cut by the cutting device and discharged outside the machine via the straw removal duct 42.

By the way, when removing the threshing machine 11 on the machine stand 3 from the machine stand 3 after completing such threshing work, first remove the grain lifting cylinder 33 and the transmission case 56, and then remove only the threshing machine 11 from the machine stand 3. If you pull it out in the direction of the arrow in Figure 2 (to the left),
The opening/closing levers 52 and 53 integrally formed on the proximal end cylinder portions 44a and 45a of each opening blade 44 and 45 come into contact with the brackets 54 and 55 on the machine base 3, and when the threshing machine 11 is pulled out to the left, the As shown in Figure 5, each open plate 44°4

It rotates counterclockwise in Figure 5 using the fulcrum as a fulcrum, and as a result,
The lower surfaces of the first gutter 20 and the second gutter 23 are opened, and the paddy remaining in each gutter 20, 23 can be taken out onto the residual paddy receiving stand 43.

It goes without saying that a spring may be applied to the opening plates 44, 45 to quickly open the plates 44, 45.

In this way, after the remaining paddy in the gutters 20 and 23 are dropped onto the pedestal 43, the threshing machine 11 is further pulled out to the left and removed from the top of the machine pedestal 3 as shown in Fig. 6. Afterwards, if the threshing machine 11 is completely removed, the self-propelled threshing machine can be used as a transporter.

Conversely, in order to mount the threshing machine 11 in the state shown in FIG. After that, when the opening/closing lever 52.53 is rotated clockwise, the opening plate 44.45
The hook-shaped parts 44b and 45b formed at the free ends of the leaf spring 50
, 51, the lower surface of the valley gutter 20.23 can be closed off with these open plates 44.45 as shown in FIG.

As described in detail above, the present invention provides a self-propelled threshing machine in which a threshing machine 11 having a first grain take-out part 22 and a second grain take-out part 25 is removably mounted on a machine base 3. Valley gutter 20, 2 in the second grain removal section 22.25
